ACQ indoors?

my question is,
Is Top Choice ACQ Type d -2 X 4 lumber permitted to be used indoors as studding for a finished basement, I will build a wall approx 2 " from masonry, I know the plates need to be press treated, but i want to use pressure treated for the studs also, are there any codes against this or are there any hazards to be concerned about.
Please respond.

I don't now about code, but I would be worried more about twisting/warping. PT seems to do a lot of that.

There's no code that prohibits doing it, but it is a terrible idea. The building inspector will probably tell you that as well. No offense intended, but if it were a good idea, you'd see professionals doing it.

It will look great until you turn your furnace or air conditioner on, and the stuff really starts drying out. Southern Yellow Pine goes CRAZY when the moisture evacuates from it.

Use ACQ for your bottom plate and frame the rest of the basement with untreated lumber. The only application where ACQ should be used indoors is when it is in direct contact with concrete.

Trust me on this.

It is not a code problem, but a very bad idea. Unless you are willing to use all #1 KDAT (read$$$$), the other stuff will warp, twist, and shrink so bad that you will regret it, gauranteed.

ACQ will also eat up conventional sheetrock screws or nails,on top of twist and warp problems.
